Import Beta-Cyclodextrin — Buy in wholesale FOB from Supplier in China

Beta-cyclodextrin is a cyclic oligosaccharide composed of seven alpha-1,4-linked glucose units, produced enzymatically from hydrolysed starch by cyclodextrin glycosyltransferase (CGTase). Jiangsu Fengyuan Biotechnology Co., Ltd manufactures this as a white powder with a hydrophobic cavity capable of forming inclusion complexes with guest molecules. The CAS number is 7585-39-9, with molecular formula C42H70O35 and molecular weight 1134.98. The toroidal structure presents an internal diameter of 0.7-0.8 nm, defining its molecular encapsulation capacity for compounds of matching geometry.

The supplier specifies total sugar content at minimum 86.5% and assay at minimum 99.0%, with moisture content capped at 12.0% and residue on ignition at maximum 0.1%. Specific optical rotation falls between +159 degrees and +164 degrees, a key identity parameter for cyclodextrin stereochemistry. Heavy metal limits are set at maximum 0.0005% and arsenic at maximum 0.0001%. Microbial specifications include total bacteria count at maximum 1000 CFU/g, moulds and yeasts at maximum 200 CFU/g, and absence of Escherichia coli. These parameters align with typical pharmaceutical and food-grade cyclodextrin standards, though buyers should confirm Jiangsu Fengyuan's testing methodology and accreditation status.

Primary applications span food stabilization, where beta-cyclodextrin complexes volatile flavours, masks bitter tastes and protects against oxidative degradation, through to pharmaceutical formulation where it enhances solubility and bioavailability of poorly water-soluble drugs. The compound also finds use in cosmetics and chemical industries. Buyers include flavour houses, pharmaceutical excipient distributors and functional food developers. Water solubility of 1.85 g/100 mL at ambient temperature limits some applications, though complexation with guest molecules can modify this. Trade terms with Jiangsu Fengyuan require direct negotiation, as the listing presents product specifications without stated MOQ, pricing structure or lead time.

Jiangsu Fengyuan Biotechnology Co., Ltd is located in Sanchuang Property Zone, Suqian, Jiangsu Province 223800, China, a region with established chemical and biotechnology manufacturing infrastructure. The supplier holds a harbour trust tier classification. The response rate is recorded at 0.00% with zero average response hours, indicating no platform-mediated communication history. Buyers should anticipate initiating contact through available channels and may need persistence to establish initial dialogue.

The listing provides substantial technical detail on beta-cyclodextrin specifications and applications, suggesting direct manufacturing or focused trading expertise in cyclodextrin chemistry. No information is given on company history, workforce size, revenue, manufacturing capacity, client base, or certifications such as ISO, GMP or FSSC 22000. The address in Suqian's industrial zone may represent manufacturing, warehousing or office functions. Buyers should request facility audit access, quality system documentation and regulatory compliance files directly from Jiangsu Fengyuan before committing to volume orders.
